I moved to the University of Rome (Sapienza), here is my new webpage.

Research interests: I usually work on problems involving geometric structures on surfaces and 3-manifolds.
I have a special interest for hyperbolic geometry, so my motivation often comes from the connections with one of the following topics:

Hyperbolic surfaces and hyperbolic 3-manifolds
Kleinian groups
(Higher) Teichmüller theory
